A fourth-generation Montana rancher, Lyman investigated the use of chemicals in agriculture after developing a spinal tumor that nearly paralyzed him. Now a vegetarian, he blasts through the propaganda of beef and dairy interests -- and the government agencies that protect them -- to expose an animal-based diet as the primary cause of cancer, heart disease, and obesity in this country. He warns that the livestock industry is repeating the mistakes that led to Mad Cow disease in England while simultaneously causing serious damage to the environment.
